4.3.3.3 Switch on Sequency Pneumatic Units
Fig. 4.3 - 6 switch on sequency pneumatic
Please Note: Prop. valve X58, controlled by relay K2, is immediately powered with machine ON.
After the reference run is performed, the valve X58 can be switched off by soft-
ware (as a standard 2 minutes).
The time to deactivate the prop. valve can be changed in station software

4.3.3.4 Main Valve , main regulator X59 for machine components
After the machine is switched on with the main switch, the valve is powered and air runs into the
system. Opening any cover, for e.g, has no effect to the air supply. Only when the 24V power is
missing or the machine is switched off, the valve close and
no air is supplied to the docking sta-
tion (co-table), as well as via X60 to the tape cutter and PCB transport system. If the pressure is
too low, the A/D converter provides an output of 24 VDC. This signal is supplied via the CAN I/O
module in section 4 (pressure too low) and via the CAN bus to the machine controller. The valve
X59 is controlled by K1, located in section 4, sub-distributor.
The pressure for this 5/2 valve is manually adjusted by a throttle to 5 +0.1 bar.
NOTE: This main pressure regulator can be damaged if the machine is turned on without com-
pressed air supplied. Therefore if the compressed air supply fails, turn of the machine.
